Aubameyang arrival to Barcelona is considered very appropriate, because Barcelona will have a big match Vs Atletico Madrid. Xavi can immediately play Aubameyang because Aubameyang's condition is very good. As a new player, of course have to adapt to the team that just defended. Barcelona Style of play suits Aubameyang very well, moreover he has a very good goal-scored instinct.
I am happy with the arrival of two new Barcelona players in January, hopefully it can help Barcelona improve their form. I hope they both get the chance to play their first game against Atletico Madrid in the next few days, they are expected to be good for Barcelona's attack.
Xavi can directly experiment at once by playing Aubameyang and Adama Traore at the same time. Adama strong character can make Atletico Madrid defenders have to take special care of Adama, this opportunity can be used by Aubameyang to score goals easily.
It's not that easy, mamesso. They need adaptation and maybe that will hinder their early performances during the game. But I believe Aubameyang and Traore can prove their capacity as good players for Barcelona. It would be nice if they managed to score goals, it would make the team even more motivated to develop.
